Help Please

I was dragging last night at the local 1/8th mile. I warmed up the bike, then made a smooth, clean pass, not pushing the bike to far.

 

Then I made some fast runs, fastest I've ever done. I was pushing the bike so hard that a plug broke loose a bit, and I didn't realize it.

 

I let it cool down for a while, then I got bored of racing and started messing around a bit in an open field. I guess while winding it out, the plug backed out even more.

 

I stopped messing around, and parked it, letting the bike (and myself) rest, because I was beat.

 

Then I see a friend from about an hour and a half away, on his modded 'Shee at the track, and he wanted to run.

 

So, I decided to, not using good judgement. Being my last run of the night, I decided to spin my tires (to get dirt and water off too.) I ripped through the gears, and the plug backed out even more. I let off the brake, and ride out my burn out to the light. I noticed it had a bog, and it was really hot. Since it's Florida, and I was wearing full riding gear from the Gixxer, I didn't think much of it. I go, and bog, and have a horrible run.

 

I know at this point something HAS to be wrong. (I was about 2 whole seconds off my time.) I bring it over, and kill it. Seconds later, I hear a hiss, and it boils over, with steam pouring out. I was to afraid to restart it because of what was happening, and I knew I should have rode it out instead of shutting it down. But I shut it down before it boiled over.

 

(I run Engine Ice.)

 

Anyways:

 

What all do I need to check for damage?

 

I am going to drain all the coolant, and flush the system.

 

I am going to order new plugs.

 

I am going to inspect the parts of the bike I can see for damage.

 

I am going to inspect the radiator and it's hoses.

 

I am going to check the shitty stock impeller, and order a billet one.

 

I will be parking the bike for about a month, and I'm bringing it to the shop to have all my mods installed. I am going to have them check the cylinders and rings too.

 

What else is there?

sounds like you got your bases covered.. but I'd also throw a leak down in there for shits and giggles to rule out a possible air leak.

[kawiking]

thats sucks

[05.Banshee.SE]

Thanks for the fast response.

 

I will throw that in with a compression test.

 

On a scale of 1-10, how bad do you think the damages could be?

(Obviously no one knows for sure yet.)

 

Within minutes of the boil over I had it in the bed of my truck, running through the back roads of Florida at about 80mph with a hell of a lot of cool wind flowing through it.

probably isn't too bad.. If leak down and compression come back good.. Dbl check your impeller like you said. If them things all check out.. start'er up and run it.

i would do a comp test it sounds like when i broke a ring. i got away with new rings and gaskets :thumbsup: i hope your that lucky.

Did your spark plugs back out? If your spark plug backed out you need to find out why it back out. Do you have any thing done to it?

[fastbanshee8]

I agree with the above post. If your spark plug backed out, then it's probably from detonation, and you could be replacing a lot of parts. It's never a good sign, if a spark plug backs out.

[05.Banshee.SE]

It's all stock right now.

 

Is there anyway I can start it and warm it up to at least do a comp test?

 

I have some spare engine ice left...all I need is it warmed up for 5 minutes... I'm afraid it will do more damage though.

 

A cold comp test won't be that accurate.

 

 

Other than not installing it correctly, why would a plug back out?

 

I won't have such a hot running bike once I bring it to the shop. I'm having a cool head, domes, exhaust, pods, tors removed, all that stuff, so it will run much cooler.

 

Edit--

 

I might just have a top end rebuild when I bring it in too.

[05.Banshee.SE]

I'm going to hope the spark plug wasn't installed to specification.

 

Edit-

 

My first post is all what I think happened. I have no idea if that's exactly how it went, with the plug backing out and such, but it sounds logical.

[shee4speed]

a cold comp.test is just fine. did you lose all your coolant? maybe you just didnt get the plug tightened all the way,being stock.I say fill up the coolant and fire it up after doing a comp. check. see if the coolant is flowing through the motor.

[05.Banshee.SE]

Bad news...the cold comp test registered about 90psi on each cylinder!

 

I feel my wallet shrinking...

 

Edit-

 

I'm going to get a second compression check from another gauge when I get a chance. May not be til it hits the shop.

[shee4speed]

that sucks. You dont have many hours on her do ya? still doesnt explain it getting hot.

I'm not to suprised by the comp test to be honest... I have a good amount of hours on it, and was planning to rebuild soon. I was hoping it wouldn't be THIS soon.

 

About 85% of the hours I'd say are regular trail riding, and 15% being race/messing around.

 

I bought it used with low hours. (The guy had nowhere to ride, and kept it in his shed. His son mostly drove it around the neighborhood, and in the yard which was not very big.)

 

I don't think it even saw a trail before I got a hold of it.

You holding the throttle wide open when doing your compression test? Plugs backing out and it running hot sounds like it could be a timing issue. If your timing is to much it could cause detonation. Which in turn makes the bike hot and backs the plugs out. Maybe a little lean in your jetting? Just some thoughts
